Von Schweikert 4jr cables?

I need to buy cables for my 4jr. This will be a long run (16'), so I some cables that I could afford for a short run will be too expensive for this length. I'd also like to biwire, since VSA recommends that so highly, and this of course will add to the cost. Right now I have a pair of Golden Tube SE40s used as monoblocks for 80 watts per channel, but I may experiment later with more powerful amps.

Any suggestions? Thanks!
